Mesa 25.1 is out today as the new quarterly feature release for this set of open-source user-space graphics drivers primarily consisting of OpenGL and Vulkan driver support on Linux systems.
The Vulkan drivers within Mesa continue to be the biggest focus in recent years. Mesa 25.1 brings a number of new Vulkan extensions to the Intel ANV and Radeon RADV drivers as well as the smaller drivers too like PanVK for Arm Mali, V3DV for Raspberry Pi, NVK for NVIDIA GPUs, etc.
Plus Mesa 25.1 has improvements to the Rusticl OpenCL driver, continued work on the Zink OpenGL-on-Vulkan driver, improvements for the Radeon RX 9000 series RDNA4/GFX12 support, newer Arm Mali 4th Gen hardware support in Panfrost and PanVK, the Intel Linux graphics driver will be less restrictive over RAM use, deprecating Gallium Nine, various Intel Xe2 / Battlemage graphics improvements, Clover is deprecated in favor of Rusticl, Vulkan ray-tracing support for the Venus driver, Chromium VA-API support, GMLIB for the RadeonSI driver in working on HDR video support, Wayland color management for the Vulkan WSI, low-latency encoding for the RADV Vulkan Video handling, and a variety of other new features and performance optimizations.
Today’s release announcement for Mesa 25.1 sums up the highlights as:
